simple, eflicient, durable, inexpensive and which may be readily andinexpensively installed.

The same also has as an object the production of a device of the kinddescribed which may be installed without additional fastening means orwith use of tools which may be made in a variety of sizes to fitdifferent constructions, but which does not require exact size wherethere is slight variation in the dimensions of window frames ofdifferent windows or in the same window.

Many other objects and advantages of the construction herein shown anddescribed will be obvious to those skilled in the art from thedisclosure herein given. I

To this end my invention consists in the novel construction, arrangementand combination of parts herein shown and described, and moreparticularly pointed out in the claims.

In the drawing, wherein like reference characters indicate like orcorresponding parts:

Fig. 1 is a perspective view of a portion of the window frame and sashframe with the weather strip applied;

Fig. 2 is a perspective view of a portion of a window frame showingapplication of the strip to the side of the frame; and

Fig. 3 is a perspective view of a portion of a strip before applicationto the frame.

Referring to the drawing, in which only one embodiment of the inventionis shown, it may be mentioned that the window frame and sash frameillustrated in the drawing are typical of the usual construction, theframe being, of course, car ried by the building structure and the sashbeing hinged to the window frame so as to swing in the desireddirection.

The weather strip is preferably made from sheet spring metal, such asspring bronze metal or the equivalent, which has resiliency and whichwill not corrode. The sheet of metal, which may be comparatively thin,is in the form of a strip of the desired width and length which isrolled, folded or bent to provide the strip proper and integrally formedmeans for securing the strip in place. In the strip illustrated thestrip is formed with a portion I having one edge rolled over asindicated at 2 and thence bent as at 3 to provide a cooperating strip 4.The strip portions l and 4, as will be noted, are connected by a rolledover or intermediate portion without a sharp reverse bend so that theintermediate portion in a way constitutes a resilient hinge, the wholemore or less resembling a V-shaped structure with the point of the Venlarged. The strip is secured in place by mounting the same upon thestop on the window frame so that the strip portions I and 4 areinterposed between the stop and the window sash. Y

As shown, the free edge of the strip portion 4 is folded back uponitself at 5 and extends as at 6 in proximity to the portion 4. The sameis then bent laterally away from 4 as indicated at l to provide aportion 8 which extends substantially at a right angle to the part 6 andis adapted to seat upon the face of the stop frame. The ex- .treme edgeof the metal sheet is bent over as at 9 so as to provide the sideportion III which is arranged to cooperate with portion 6 to form a stopclamp, whereby the weather strip is secured to the window stopandmaintained in place without other fastening means. It will be seen byreferring to Fig. 3 that the bend at 9 is suflicient to bring theextreme free edge of the portion 10 toward the portion 6 so that whenthe device is fitted to a window stop part i0 is'under tension. It isgenerally preferred to form a bead or slight bend H at the juncture ofthe strip I and the intermediate portion 2 and to slightly turn over theedge I! so as to provide a rolled edge where the strip first comes incontact with the window sash.

Referring to Fig. 1, l5 represents the metal window frame which isprovided with a window stop i6 and may be flanged as indicated at ll.The window frame also has the side frames formed as indicated at l8, l9and 20. A typical sash frame is shown in Fig. 1 made up of the angle 23,24 and 25 which is hingedor operatively secured to the window frame inany suitable or desired manner, usually hinged at one side of the windowframe and provided with means at the opposite side for locking the samein closed position.

The weather strip is applied to the frame of the window by seating thesame on the flanges or stops it at the top and bottom and H at thesides. It is easily positioned by seating the member ID and positioningthe device over the stop with the side or end portion of the channel 8seated upon the face of the stop with the stop tightly clamped 29 on,the portion ID of the channel which will between the sides 6 and I0.When so arranged the engage directly with the frame, either at the lowertension or resiliency of the metal is sumcient to edge of the flange IEor in a groove 30 (see Fig. l) secure the strip in operative positionand mainwhich may be formed in the frame.
